The “Google Myth”


Why Do Students LikeGoogle and Google

Scholar?

•It’s fast•It’s easy to use•It’s relevant•It’s FREE


Library vs. Internet

“Nearly three-quarters (73%) of college students say they use the Internet more than the library, while only 9% said they use the library more than the Internet for information searching.” *Pew & Internet American Life, 2002

Students Looking for Information




What Students Don’t Know

1. Links for many articles on Google Scholar require subscriber login or an access fee.

2. Many libraries have already paid for subscriptions.

3. Other content may be more relevant to the topic.

4. Google Scholar advanced search is not very powerful.


So Why NOT Google Scholar?

• “Scholarly content” intermixed with “non-scholarly” content

• Spotty coverage, requires publisher cooperation

• Poor relevance (citation counts don’t seem to help)

• Unable to limit searching to specific sources

• Difficult to find the needles in the haystack

Tennant’s Tenets

• Only librarians like to search, everyone else likes to find.

• All things being equal, one place to search is better than two or more.

• Services should be placed as close to the user as possible.

Roy Tennant: Internationally known speaker and writer on library and information technology issues.


Tennant’s Tenets (cont.)

•“Good enough” is often just that.•Our ability to create effective one-

stop searching is dependent on our ability to appropriately target user needs.

•The size of the result set doesn’t matter as much as how the results are presented. (‘the Google Lesson’)


How can Federated Search Help Your Users?


Benefits of Federated Search

•One-Stop Access•Support of More Efficient

Research•Consolidated, Formatted Results•Authentication and Access

Control


One-Stop Access

Single query search across multiple disparate sources in real-time:

–Subscription services (journals, bibliographic databases, etc.)

–In-house databases

–Unstructured data (white papers, theses, reports, etc.)

–Catalogs (web-based OPAC)

–Publicly available databases

Information Discovery


Support of More Efficient Research

Results across all selected sources are:

–Merged–Presented in relevance-

ranked order–Sorted–Clustered


Consolidated, Formatted Results

•Filter and remove duplicates•Rank by relevance•Display results by source•Permit results to be

– Downloaded– Printed– Automatically emailed using Alerts


Authentication and Access Control

•Authorization based on:– IP address– User ID and password

•Implementation using:– Proxy server– Link resolver– Management of session cookies

•Different access levels for different user groups

– Search Builder
